Description

Vibration absorbing coupling
Technical field
The present invention relates to automobile technical field, specifically, is a kind of vibration absorbing coupling that is used on electric vehicle, is used for connecting between motor and speed changer.
Background technique
Connecting between the motor of electric vehicle and speed changer, generally adopt rigid coupling, because it does not need gearshift, the impact shock that does not exist gear shift to bring, the vibration of transmission system is also not too obvious on the impact of motor.Day by day abundant along with the electric vehicle theory, speed changer is replaced by two grades of automaitc shfit or multi-speed transmission, and gear shift inevitably produces impact, and the vibratory impulse that rigid coupling produces can't absorb work between motor and speed changer the time; Moreover the vibration of transmission system itself also can have a negative impact to motor, also can reduce reliability and the life-span of motor and transmission system component.Due to the compact structure of electric motor car, the ordinary elasticity coupling of various types can not directly be selected because of problems such as reliability reaches axially, radial dimensions.Therefore, need a kind of coupling with vibration-damping function of redesign, effectively improve institute and connects impact between diaxon, transmission is moved and torque.
Summary of the invention
The object of the present invention is to provide a kind of vibration absorbing coupling of compact structure, can effectively subdue shifting of transmission and impact, reduce driveline vibrations to the adverse effect of motor, improve reliability and the life-span of motor and transmission system component.
For solving above technical problem, a kind of vibration absorbing coupling provided by the present invention, vibration absorbing coupling, comprise flange plate (1), driven plate (2), hub (3), damping disk(-isc) (4) and shock-absorbing spring (5), key is: the right-hand member of described flange plate (1) stretches out into one uncovered (1a), described uncovered (1a) outer rim is with the flanging (1b) vertical with flange plate (1) axis, and the flanging (1b) of described flange plate (1) is connected by equally distributed the first rivet (9) on circumference with driven plate (2); Described hub (3) is made of hub former (3a) and hub core (3b), be set with the first damping washer (6) on the hub core (3b) in described hub former (3a) left side, T-shaped and the left end external diameter of described the first damping washer (6) is less than the right-hand member external diameter, and described driven plate (2) is sleeved on described the first damping washer (6) left end excircle and the right side of this driven plate (2) is pressed on the step of the first damping washer (6); From left to right be set with successively the second damping washer (7), space washer (10), butterfly spring (8) and damping disk(-isc) (4) on the hub core (3b) on described hub former (3a) right side; Described driven plate (2), hub former (3a) have strip hole corresponding to position in a circumferential direction with damping disk(-isc) (4), described shock-absorbing spring (5) is arranged in described strip hole, connect by equally distributed the second rivet (11) on circumference between described driven plate (2), hub (3) and damping disk(-isc) (4) three, described hub (3) is driven plate (2) and damping disk(-isc) (4) rotation angle α relatively, and-14 °≤α≤14 °.
Adopt above technological scheme, flange plate is sleeved on the output shaft of drive motor, and hub is sleeved on the input shaft of speed changer, links together by the present invention between motor and speed changer.When motor operation, the output shaft of motor drives flange plate and synchronously rotates, rotate together with the driven plate that flange plate drives with it is riveted together, because hub can be rotated certain angle relative to driven plate and damping disk(-isc), driven plate compressing shock-absorbing spring, make shock-absorbing spring promote hub and rotate, to hub, the final transmission outputs on speed changer with transmission of power.The impulsive load of driven plate quick rotation is absorbed by damping spring, and shock-absorbing spring has played buffering and rotated the effect of impacting and avoiding torsional vibration generation resonance; The space washer that hub former right side arranges compresses the location to damping washer, and the damping value of butterfly spring capable of regulating damping washer makes the damping of product uniform and stable.
The right side of above-mentioned space washer (10) is provided with four projections (10a) that distribute by even circumferential, described projection (10a) is along the Axis Extension of space washer (10), and this projection (10a) passes the endoporus of butterfly spring (8) and stretches out from damping disk(-isc) (4).
The outer long side of above-mentioned driven plate (2) strip hole becomes the first limited wall (2a) towards the direction outward flanging opposite with hub former (3a), the outer long side of described damping disk(-isc) (4) strip hole also becomes the second limited wall (4a) towards the direction outward flanging opposite with hub former (3a), and described the first limited wall (2a) and the second limited wall (4a) consist of " eight " font.
In order to facilitate manufacturing, have the arc long nick (3c) that passes through for the second rivet (11) on above-mentioned hub former (3a) excircle, have the circular hole that passes through for the second rivet (11) on driven plate (2) and damping disk(-isc) (4).
The endoporus of above-mentioned flange plate (1) is the flat key hole, and the endoporus of described hub (3) is splined hole.Flange plate is contained in by the flat key borehole jack on the output shaft of drive motor, and hub is sleeved on the input shaft of speed changer by splined hole.
Beneficial effect of the present invention:
1) hub is designed to hub former and hub core two-part, increased the design space of shock-absorbing spring, the shock-absorbing spring of large rigidity obdurability can be installed, product has in use been started to walk more smooth-going, avoid vibration damping compressive strain, fracture damage phenomenon, to extend the working life of shock-absorbing spring.
2) damping washer has increased friction area, and the coefficient of waste is stable, and the deformation principle of damping disk(-isc) employing butterfly spring compensates the wearing clearance of axial part, has guaranteed that damping is more stable, and performance is more superior.。
In sum, the present invention utilizes the working principle of clutch to carry out ingenious design, it is simple and reliable for structure, can effectively absorb the vibrational energy that produces when working between motor and speed changer, reduce the vibration in the operating modes such as electric vehicle starting, braking, anxious acceleration, anxious deceleration, avoid because impacting, transmission system and motor being had a negative impact, damping property is superior, has improved the travelling comfort of car load.
